AUTQMATIC FAN.

SPECIFICATION forming part of Letters Patent No. 299,364, dated May 2'7, 1884.

Application filed February 7, 1884. (N0 model.)

To 60% whom it may concern.-

Be it known that I, LOGAN WV. EVERHART, of Parsons, in the county of Labette and State of Kansas, have invented a new and useful Improvement in Automatic Fans, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.

This invention relates to fly fans or brushes which are operated by clock mechanism; and the invention consists of the construction hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my invention, showing the fan suspended from a ceiling. Fig. 2 is a side elevation of a clock-work for operating the same, and Fig. 3 is a detail plan View.

A indicates a frame or box having a pulley, B, supported in one end thereof, and a pin, 0, in the other, on which pin is placed an endless rubber band, D. Vi'thin the said band is placed another pin, E, the ends of which are connected to a cord, F, which is passed around the pulley B and wound on a drum, G, to, which is connected the train of gears H I J. The lower end of the shaft K of the gear-J projects through a stationary hub or pulley, L, and is rigidly connected to the center of a bar, L, which it carries. The train of gears is arranged to act in the manner of clock-work when the band or rubber spring is put under tension by winding the cord F on the drum G.

In opposite ends of the bar L are loosely supported two shaft-s, M N, to which are rigidly secured the pulleys O P, and to the lower ends of which are secured the cross-bars or brush-holders Q. Two endless bands, R R, connect the pulleys O P, respectively, with the stationary hub L. WVith this construction, as the shaft J is rotated by the clock-work, the bar L is carried around with it, and the bands 7 R Rare made to travel, rotating the pulleys 0 P, and with them the brushes. The crossbars of the brush-holders are to be provided with strips of wood secured thereto by screws, 4 5

to form a clamp for holding the brush material or paper ribbons P.

Instead of using the rubber spring above described, an ordinary clock-spring may be employed. The clock-work in either case is to be properly incased.

The fan or brush is to be suspended from a ceiling, Q, over a table or bed, &c., and in order that it may be raised or lowered to suit convenience, the two branches T T of the suspending-cord, which are attached to opposite ends of the frame or box A, are passed through separate supports U in the ceiling and a common support in the wall, and the main cord is secured to a suit-able holder at Y on the wall. By letting out or taking up the cord the fan may be supported at any desired height.

What I claim is 1. The combination, with a suitable motor, of the stationary pulley L, rotary shaft J carrying crossbar L, rotary brush-holders Q, and pulleys O P, supported at the ends of bar L, and the endless bands R R, connecting pulleys O P with the stationary pulley L, substantially as shown anddescribed.

2. The combination of the rotary fans, the train of gears and the rubber spring and cord, and the pulley and drum for winding the cord to put the spring under tension, substantially as shown and described.

3. The combination of the rotary fans, the clock-work for operating the same, and the "cord having branches T T attached to opposite ends of the fan-case, and supports for suspending the same adjustably from a ceiling, substantially as shown and described,
